[Open bite in children. Contribution to its study]

A statistic and processing study of 40 cases of open bite deformities in infants is proposed from exact clinical examinations, and various teleradiographic analysis (Coutand, Delaire, Tweed, Sassouni). The statistic study set off the anatomical complexity of open bite deformities. The processing study, recording the concordance among various teleradiographic techniques, clear 4 associated dysmorphic groups susceptible to allow adjusted treatment planning.
